I'm pretty sure that's a small dose. That seems like possibly half the dose I would expect. Maybe you can measure the units from the syringe.
Also what kind of syringe is that? Is that an insulin syringe? How long of a needle? I've never seen a 1cc diabetic syringe, all the ones I've seen are .5 cc/50 unit syringes. I'm a diabetic, so I'm a little curious on this one.
Good Luck!
